Kernza: Can This Breakfast Cereal Help Save the Planet?

No, it's just another BS fad, like the 20+ other plants called "saviors of the planet", "superfoods" etc -- there's one or two every 3-4 years...

Answer: no.

The planet is going to be fine. Whether we need to be saved, is an ongoing debate.

It's hard to take articles seriously when they are introduced with such headlines.

TLDR; Kernza is perennial unlike wheat and they are trying to breed this plant (like it was done with corn). Currently its seed are half the size of wheat.
